This paper deals with the extraction of wave features in elastic media. An inverse approach is proposed for the identification of wave dispersion characteristics (e.g. k-space) in one- and two-dimensional structures (1D, 2D). The proposed method is s

Vibration damping of flexible rotating rings using simple and double modes tuned vibration absorbers
Publikováno v:
2021 Fifteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials).
This paper investigates the potential of two types of locally resonant metamaterials to damp out the vibrations of flexible rotating rings. First, a classical solution using tuned vibration absorbers with only one radial mode is investigated. For thi
